5 Highlights of WP1/11, WP2/11 and WP3/11 meetings
WP1/11ITU-T draft Recommendations Q.SFPtr and Q.BNG-P4switch were planned to be consented at the WP1/11 plenary meeting (16 July 2021). However, as the baseline texts were not mature enough and required more improvement, the consenting plan has been postponed to SG11 meeting planned to take place in December 2021.
WP1/11 agreed to start five new work items, as follows:
- Q.NICE-SA “Signalling architecture of NICE (Network intelligence capability enhancement) in support of awareness capabilities” which introduces the reference points and specifies the mapping of reference points to interfaces in the architecture of NICE especially in support of awareness capabilities. It also provides the signalling requirements of the interfaces and defines the protocols used for interfaces (SG11-TD101/WP1).
- DC-SA “Signalling architecture of data channel enhanced IMS network” which presents the signalling architecture of data channel enhanced IMS network. The signalling architecture of data channel enhanced IMS network presents the requirements of data channel enhanced IMS network, specifies the framework of signalling network, and specifies the interfaces among data channel enhanced IMS network (SG11-TD102/WP1).
- TR-NCDP “Session layer network coding protocol for multicast data transmission”. This technical report provides an information about Session Layer multicast protocol based on network coding. The aim of the new protocol is to reduce the multicast traffic volume without reduction of the volume of transmitted information (SG11-TD113/WP1).
- Q.QKDN_profr “Quantum key distribution networks – Protocol framework” which specifies a framework for signalling aspects of a QKDN especially the following areas: overview of signalling and protocols for QKDN, signalling requirements for QKDN and protocol suites for QKDN (SG11-TD112/WP1).
- Q.CNCG-IC “Signalling requirements for intelligent control of cloud-network-converged networks gateway” (SG11-TD95-R1/WP1).
Also, WP1/11 achieved progress on the following ongoing work items:- Q.VoLTE-SAO-FP: Framework and protocols for signalling network analyses and optimization in VoLTE;
- Q.CIDA: Signalling procedures of calling line identification authentication;
- Q.Pro-Trust: Signalling procedures and protocols for enabling interconnection between trustable network entities in support of existing and emerging networks;
- Q.IMT2020-SAO: Requirement, framework and protocols for signalling network analyses and optimization in IMT-2020;
- Q.Sig_Req_ETS_IMS_roaming: Signalling requirements for emergency telecommunication service in IMS roaming environment;

- Q.DIVS-IMT2020 “Signalling Requirements and Protocol for Providing Network-oriented Data Integrity Verification Service based on Blockchain in IMT-2020 network” which specifies signalling requirements and protocol for providing network-oriented data integrity verification service based on blockchain in IMT-2020 network. It includes signalling requirements, protocol procedures and message format between DIVS function with the UEs, the service user, the CEF and other DIVS functions, and security considerations. (SG11-TD92/WP2).
Also, WP2/11 achieved progress on the following ongoing work items:

- ITU-T Q.4068 (ex. Q.API4TB) “Open APIs for interoperable testbed federations” which provides a generic reference model for testbeds federation and describes the elements of this reference model. This Recommendation contains a technical framework consisting of guidelines, which provides a common reference for developers in order to facilitate the implementation and promotion of interoperability of testbeds. (SG11-TD92-R1/WP3).
WP3/11 agreed to start a new work item Q.N-att-framework “Framework of NFV automated testing” (
SG11-TD88/WP3).
